6 Cat Coat Changes That Need Your Attention

Cats are famously meticulous groomers, spending much of their time keeping their coats clean and healthy. Most shorthaired cats manage their grooming effectively without help, while longhaired breeds like the sphynx require occasional brushing to prevent tangles and mats. Unlike dogs, regular bathing is rarely needed unless a cat gets into something sticky or toxic.

Yet, during grooming, it’s wise to check your cat’s coat and skin carefully. Changes in the coat can often be the first sign that something isn’t quite right with your feline friend. Below, we've outlined six key coat changes that should prompt a closer look and often a visit to your vet.

1. A Dull, Dry Coat

If your cat’s coat loses its natural sheen, looks dry, or the skin beneath appears flaky and inelastic, this could suggest nutritional deficiencies or an underlying systemic illness. Consider whether your cat’s diet provides all necessary nutrients, and if improving their food doesn’t help, seek veterinary advice to rule out health issues.

2. Hair Loss or Excessive Shedding

While seasonal shedding is normal, patchy hair loss or overall thinning is a concern. Causes range from stress and allergies to fungal infections like ringworm or chronic conditions such as Addison’s disease. Prompt veterinary assessment is recommended to diagnose and treat any underlying problem.

3. Longer, Thicker, or Unusual Hair Growth

Noticing your cat’s fur growing thicker or longer unexpectedly can indicate disorders such as Cushing’s disease, which disrupt normal hair growth cycles. This rare symptom warrants veterinary investigation to ensure timely diagnosis and treatment.

4. Matted Fur and Knots

Mats can develop if your cat is not grooming well due to illness or pain, or if their fur texture changes unexpectedly. In longhaired cats, regular grooming is essential to prevent mats, which can cause discomfort and lead to skin infections. If mats appear suddenly without grooming changes, your vet can help identify any health concerns.

5. Coat Colour Changes

While some greying with age is natural, sudden or patchy colour changes could indicate hormonal imbalances, allergies, or nutritional issues. For example, certain amino acid deficiencies can alter fur colour, and sun exposure may bleach the coat. Always investigate sudden colour changes with your vet to ensure there isn’t a hidden health issue.

6. A Tacky or Greasy Coat

A healthy cat’s coat should feel smooth and clean, never greasy or sticky. A greasy coat may signal your cat is not grooming properly, potentially due to illness or pain, or could be a symptom of hormone imbalances such as hyperthyroidism. This condition can be medically managed, so timely vet evaluation is important.

Why Regular Coat Checks Matter

Cats are skilled at hiding illness, and coat changes may be one of the earliest visible signs of health problems. Incorporate gentle grooming and coat inspection into your routine—it can provide invaluable health insights and help you catch issues early.

Always seek advice from a vet if you notice any persistent or significant changes in your cat’s coat. Responsible pet ownership includes monitoring your cat’s wellbeing beyond just their behaviour. A shiny, healthy coat often reflects a happy, well-cared-for cat.
